  41. ## 一、写在前面
  42. 我们为什么要做Zinx,Golang目前在服务器的应用框架很多,但是应用在游戏领域或者其他长链接的领域的轻量级企业框架甚少。
  43. 设计Zinx的目的是我们可以通过Zinx框架来了解基于Golang编写一个TCP服务器的整体轮廓,让更多的Golang爱好者能深入浅出的去学习和认识这个领域。
  44. Zinx框架的项目制作采用编码和学习教程同步进行,将开发的全部递进和迭代思维带入教程中,而不是一下子给大家一个非常完整的框架去学习,让很多人一头雾水,不知道该如何学起。
  45. 教程会一个版本一个版本迭代,每个版本的添加功能都是微小的,让一个服务框架小白,循序渐进的曲线方式了解服务器框架的领域。
  46. 当然,最后希望Zinx会有更多的人加入,给我们提出宝贵的意见,让Zinx成为真正的解决企业的服务器框架!在此感谢您的关注!

  53. ## 三、Zinx开发API文档
  54. ### 快速开始
  55. #### 示例演示
  56. 1. 编译demo示例,会在`zinx/example/zinx_server`下得到`server`, 在`zinx/example/zinx_client`下得到`client`.
  57. ```bash
  58. $ cd zinx/
  59. $ make
  60. ```
  61. 2. 启动Demo server, 该终端不要关闭
  62. ```bash
  63. $ cd example/zinx_server
  64. $ ./server
  65. ██

  76. [Zinx] Version: V0.11, MaxConn: 3, MaxPacketSize: 4096
  77. Add api msgId = 0
  78. Add api msgId = 1
  79. [START] Server name: zinx server Demo,listenner at IP: 127.0.0.1, Port 8999 is starting
  80. Worker ID = 0 is started.
  81. Worker ID = 1 is started.

  90. start Zinx server zinx server Demo succ, now listenning...
  91. ...
  92. ```
  93. 3. 再打开新终端,启动client Demo测试通信
  94. ```bash
  95. $ cd example/zinx_client
  96. $ ./client
  97. ==> Test Router:[Ping] Recv Msg: ID= 2 , len= 21 , data= DoConnection BEGIN... ==> Test Router:[Ping] Recv Msg: ID= 0 , len= 18 , data= ping...ping...ping
  98. ==> Test Router:[Ping] Recv Msg: ID= 0 , len= 18 , data= ping...ping...ping
  99. ==> Test Router:[Ping] Recv Msg: ID= 0 , len= 18 , data= ping...ping...ping
  100. ...
  101. t
  102. ```
  103. #### server
  104. 基于Zinx框架开发的服务器应用,主函数步骤比较精简,最多只需要3步即可。
  105. 1. 创建server句柄
  106. 2. 配置自定义路由及业务
  107. 3. 启动服务
  108. ```go
  109. func main() {
  110. //1 创建一个server句柄
  111. s := znet.NewServer()
  112. //2 配置路由
  113. s.AddRouter(0, &PingRouter{})
  114. //3 开启服务
  115. s.Serve()
  116. }
  117. ```
  118. 其中自定义路由及业务配置方式如下:
  119. ```go
  120. import (
  121. "fmt"
  122. "github.com/aceld/zinx/ziface"
  123. "github.com/aceld/zinx/znet"
  124. )
  125. //ping test 自定义路由
  126. type PingRouter struct {
  127. znet.BaseRouter
  128. }
  129. //Ping Handle
  130. func (this *PingRouter) Handle(request ziface.IRequest) {
  131. //先读取客户端的数据
  132. fmt.Println("recv from client : msgId=", request.GetMsgID(), ", data=", string(request.GetData()))
  133. //再回写ping...ping...ping
  134. err := request.GetConnection().SendBuffMsg(0, []byte("ping...ping...ping"))
  135. if err != nil {
  136. fmt.Println(err)
  137. }
  138. }
  139. ```
  140. #### client
  141. Zinx的消息处理采用,`[MsgLength]|[MsgID]|[Data]`的封包格式
  142. ```go
  143. package main
  144. import (
  145. "fmt"
  146. "io"
  147. "net"
  148. "time"
  149. "github.com/aceld/zinx/znet"
  150. )
  151. /*
  152. 模拟客户端
  153. */
  154. func main() {
  155. fmt.Println("Client Test ... start")
  156. //3秒之后发起测试请求,给服务端开启服务的机会
  157. time.Sleep(3 * time.Second)
  158. conn,err := net.Dial("tcp", "127.0.0.1:7777")
  159. if err != nil {
  160. fmt.Println("client start err, exit!")
  161. return
  162. }
  163. for n := 3; n >= 0; n-- {
  164. //发封包message消息
  165. dp := znet.NewDataPack()
  166. msg, _ := dp.Pack(znet.NewMsgPackage(0,[]byte("Zinx Client Test Message")))
  167. _, err := conn.Write(msg)
  168. if err !=nil {
  169. fmt.Println("write error err ", err)
  170. return
  171. }
  172. //先读出流中的head部分
  173. headData := make([]byte, dp.GetHeadLen())
  174. _, err = io.ReadFull(conn, headData) //ReadFull 会把msg填充满为止
  175. if err != nil {
  176. fmt.Println("read head error")
  177. break
  178. }
  179. //将headData字节流 拆包到msg中
  180. msgHead, err := dp.Unpack(headData)
  181. if err != nil {
  182. fmt.Println("server unpack err:", err)
  183. return
  184. }
  185. if msgHead.GetDataLen() > 0 {
  186. //msg 是有data数据的,需要再次读取data数据
  187. msg := msgHead.(*znet.Message)
  188. msg.Data = make([]byte, msg.GetDataLen())
  189. //根据dataLen从io中读取字节流
  190. _, err := io.ReadFull(conn, msg.Data)
  191. if err != nil {
  192. fmt.Println("server unpack data err:", err)
  193. return
  194. }
  195. fmt.Println("==> Recv Msg: ID=", msg.Id, ", len=", msg.DataLen, ", data=", string(msg.Data))
  196. }
  197. time.Sleep(1*time.Second)
  198. }
  199. }
  200. ```
  201. ### Zinx配置文件
  202. ```json
  203. {
  204. "Name":"zinx v-0.10 demoApp",
  205. "Host":"127.0.0.1",
  206. "TcpPort":7777,
  207. "MaxConn":3,
  208. "WorkerPoolSize":10,
  209. "LogDir": "./mylog",
  210. "LogFile":"zinx.log"
  211. }
  212. ```
  213. `Name`:服务器应用名称
  214. `Host`:服务器IP
  215. `TcpPort`:服务器监听端口
  216. `MaxConn`:允许的客户端链接最大数量
  217. `WorkerPoolSize`:工作任务池最大工作Goroutine数量
  218. `LogDir`: 日志文件夹
  219. `LogFile`: 日志文件名称(如果不提供,则日志信息打印到Stderr)
  220. ### I.服务器模块Server
  221. ```go
  222. func NewServer () ziface.IServer
  223. ```
  224. 创建一个Zinx服务器句柄,该句柄作为当前服务器应用程序的主枢纽,包括如下功能:
  225. #### 1)开启服务
  226. ```go
  227. func (s *Server) Start()
  228. ```
  229. #### 2)停止服务
  230. ```go
  231. func (s *Server) Stop()
  232. ```
  233. #### 3)运行服务
  234. ```go
  235. func (s *Server) Serve()
  236. ```
  237. #### 4)注册路由
  238. ```go
  239. func (s *Server) AddRouter (msgId uint32, router ziface.IRouter)
  240. ```
  241. #### 5)注册链接创建Hook函数
  242. ```go
  243. func (s *Server) SetOnConnStart(hookFunc func (ziface.IConnection))
  244. ```
  245. #### 6)注册链接销毁Hook函数
  246. ```go
  247. func (s *Server) SetOnConnStop(hookFunc func (ziface.IConnection))
  248. ```
  249. ### II.路由模块
  250. ```go
  251. //实现router时,先嵌入这个基类,然后根据需要对这个基类的方法进行重写
  252. type BaseRouter struct {}
  253. //这里之所以BaseRouter的方法都为空,
  254. // 是因为有的Router不希望有PreHandle或PostHandle
  255. // 所以Router全部继承BaseRouter的好处是,不需要实现PreHandle和PostHandle也可以实例化
  256. func (br *BaseRouter)PreHandle(req ziface.IRequest){}
  257. func (br *BaseRouter)Handle(req ziface.IRequest){}
  258. func (br *BaseRouter)PostHandle(req ziface.IRequest){}
  259. ```
  260. ### III.链接模块
  261. #### 1)获取原始的socket TCPConn
  262. ```go
  263. func (c *Connection) GetTCPConnection() *net.TCPConn
  264. ```
  265. #### 2)获取链接ID
  266. ```go
  267. func (c *Connection) GetConnID() uint32
  268. ```
  269. #### 3)获取远程客户端地址信息
  270. ```go
  271. func (c *Connection) RemoteAddr() net.Addr
  272. ```
  273. #### 4)发送消息
  274. ```go
  275. func (c *Connection) SendMsg(msgId uint32, data []byte) error
  276. func (c *Connection) SendBuffMsg(msgId uint32, data []byte) error
  277. ```
  278. #### 5)链接属性
  279. ```go
  280. //设置链接属性
  281. func (c *Connection) SetProperty(key string, value interface{})
  282. //获取链接属性
  283. func (c *Connection) GetProperty(key string) (interface{}, error)
  284. //移除链接属性
  285. func (c *Connection) RemoveProperty(key string)
  286. ```
